Players who completed the quest chain prior to the opening of the Temple of Ahn'Qiraj will receive the Scarab Lord title and the Black Qiraji Resonating Crystal mount. GMs will be adding these manually over the next week so it's probably most efficient if you have a ticket opened while you're online.

Kandrostrasz <Brood of Alexstrasza> in Temple of Ahn'Qiraj will offer 7 repeatable quests to players who have the enchanting skill with 300 skill points which allow the enchanter to obtain materials which are actually TBC materials but are needed for some enchanting recipes which drop in aq20/40.

Blackwing Lair (BWL) and Ruins of Ahn'Qiraj (AQ20) are being nerfed after next restart to be in line with the other raids. This will allow doing them in less time or with less players to have an easier time preparing for current content. Especially for AQ20 the difference will be big so it should properly act like a quick catchup raid.

With the release of Naxxramas, we have applied the first nerf to the Temple of Anh'Qiraj although C'thun might not be doable until another nerf.

Naxxramas is also on a completely different level from the other raids but we're still starting with the same buff. The first nerf could be as soon as next week and even the hardcore shouldn't have too much expectations of boss kills during this time. At least trash also has a small chance for some good drops

Apart from the ability scaling, the first overal HP/mana nerf has already been applied to Naxxramas so it's now buffed to the same extend as the Temple of Anh'Qiraj.

Paladins have been buffed in this week's update. Holy Shock is no longer affected by the mana debuff so it will cost a lot less mana in raids. In addition Lay on Hands is no longer affected by the healing debuff so it will heal for the original amount in both PvE and PvP.

The second boss of each wing has been released in Naxxramas. Additional tweaks may still follow.
In addition the Temple of Anh'Qiraj has received another nerf so it's now buffed to the same extend as all previous raids.

For PvP you might notice that you suddenly receive a new honor rank at next login. The required kills have been drastically lowered so they are better distributed among players and not unreachable before TBC. In fact, there already is one Grand Marshal and one High Warlord. These are the required kills for each rank:

The third boss of each wing has been released in Naxxramas. As we continue to work and ensure content is enjoyable, additional tweaks and mechanic changes may follow depending on the community feedback. Happy raiding and good luck!
